1.1This test method provides a protocol for capturing, extracting, and quantifying the adenosine triphosphate (ATP) content associated with microorganisms found in water-miscible metalworking fluids (MWFs).

1.2The ATP is measured using a bioluminescence enzyme assay, whereby light is generated in amounts proportional to the concentration of ATP in the samples. The light is produced and measured quantitatively as relative light units (RLUs) which are converted by comparison with an ATP standard and computation to pg ATP/mL.

1.3This test method is equally suitable for use in the laboratory or field.

1.4The test method detects ATP concentrations in the range of 4.0 pg ATP/mL to 400 000 pg ATP/mL.

1.5Providing interferences can be overcome, bioluminescence is a reliable and proven method for qualifying and quantifying ATP. The method does not differentiate between ATP from different sources, for example, from different types of microorganisms, such as bacteria and fungi.

1.6The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.8This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
